You'd have to create the animations in Blender, Milkshape, Max, or...I think there's another, but I can't remember the name. And sketchup models don't import very well into those programs. Do you have an image of the sign you made?

I have found it: the held prop I was talking about is part of BongoMan's 'Guns and Swords' mod. It accepts user images but the animations are those of a gun, so, apart from holding it up, there's little to do with it, unless you know how to shoot with a protest sign.

The protest sign by BongoMan is just a variant of a gun, so instruct your puppet to use ('Use prop') whatever gun you fancy, eg the PV Walther, and then 'Customize Prop', browse thru the many variants and select the protest sign thing.

PS: do you know each and every one of your posts comes with an 'Edit' button for modifying their content? No need to create a new post every time something new related to the same subject pops into your mind, when the prior questions have not been answered yet. Just edit your last post and append your new question. That way it's much easier to get every question answered in a single response post.

Keep calm and enjoy.
